Problems solved by technology

Among them, the unit cost of photochromic materials is expensive, and the color change is single; thermochromic materials require high heat to drive; electrochromic materials have a wide color gamut and flexible control, but the color saturation is insufficient in the background of natural light; solvent-induced coloring The toning range is large and the color saturation is high, but it is difficult to achieve reversible adjustment

Embodiment 1

[0037] like figure 1 and figure 2 As shown, the color-changing material system of this embodiment includes a composite film layer 2 formed by superimposing four color film layers 1 of different colors (the colors in each color film layer 1 are red, green, yellow, and dark red respectively), Each color film layer 1 is printed with color dots 3 of different area sizes, and each color film layer 1 is movable, and the color dots 3 located on different color film layers 1 can be realized by the movement of the color film layer 1 superimposed on each other.

[0038] In this embodiment, the color dots 3 on each color film layer 1 have the same color, and the area size of the color dots 3 is gradually distributed along the X-axis, and gradually increases from left to right (such as figure 1shown).

[0039] In this embodiment, the color-changing material system further includes a color film position adjustment mechanism for realizing the position adjustment of each color film layer...

Embodiment 2

[0048] The color-changing material system in this embodiment and the color-adjusting method of the color-changing material system are the same as those in Embodiment 1 (the color of each color film layer 1 can be adjusted according to actual needs).

[0049] The color-changing material system in this embodiment is used in the field of building exterior walls to obtain a color-changing building exterior wall, and the side view of the color-changing building exterior wall is as follows: Figure 5 As shown, the color-changing building exterior wall includes an exterior wall body 101, the outer surface of the exterior wall body 101 is provided with a composite film layer 2, and the upper and lower ends of the composite film layer 2 are provided with a color film position adjustment mechanism (ie, a roller adjustment system).

[0050] In this embodiment, the color of the color-changing building exterior wall can be adjusted by the roller adjustment system, and the rolling of the rol...

Embodiment 3

[0053] The color-changing material system in this embodiment and the color-adjusting method of the color-changing material system are the same as those in Embodiment 1 (the color of each color film layer 1 can be adjusted according to actual needs).

[0054] The discoloration material system in this embodiment is used in the packaging field to obtain a large-scale color-changing packaging box, and the side view of the large-scale color-changing packaging box is as follows. Image 6 As shown, the large color-changing packaging box includes a packaging box body 102, the outer surface of the packaging box body 102 is provided with a composite film layer 2, and both ends of the composite film layer 2 are provided with a color film position adjustment mechanism (ie, a roller adjustment system).

[0055] In this embodiment, the color-changing material system in this embodiment can be selectively arranged on one or more sides of the packaging box body 102 to achieve effects such as de...

Abstract

The invention discloses a multi-color-film-layer superposition color formation-based color changing material system. The system comprises a composite film layer formed by superposing a plurality of color film layers with different colors; color dots with different areas are printed on each color film layer; each color film layer is movable; and the color dots located on the different color film layers can be superposed mutually through the movement of the color film layers. The invention further provides a color adjusting method and an application of the color changing material system. According to the color changing material system, a multi-color-film-layer superposition mechanism is adopted; through the movement of the color film layers, the areas of the mutually superposed color dots indifferent positions can be controlled to have different colors; the adjusting process is rapid, and the repeatability is good; and a complex precise instrument or an expensive reagent does not need to be used in the whole adjusting process, so that the cost is low. The color changing material system can be widely applied to the fields of garment design, artistic packaging, building outer wall design, military camouflage and the like, and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of color-changing materials, and particularly relates to a color-changing material system capable of arbitrarily adjusting color, a color-adjusting method and application thereof. Background technique [0002] Color-changing materials are widely used in digital, automotive, construction, clothing and other fields. There are four main types of functional color-changing materials according to the way they are stimulated: photochromic materials, electrochromic materials, thermochromic materials and solvochromic materials. The most typical application of photochromic materials is color-changing sunglasses: the silver halide particles in the glass interlayer are decomposed when illuminated, and the colloidal silver particles and halogen elements block the light and appear black; when the light stimulation is removed, the silver particles and halogen elements are recombined to form Colorless silver halide with transparent ...
